Horn 3 Noise

edited March 2017 in General Questions
I know this may be a tech support question but wondering if anyone else is experiencing this problem: in all the Horn 3 patches there is a distorted pitch in the background whenever I play D3 (step above middle C). It's hard to tell what pitch it is but it's dissonant and not in the harmonic series. Other notes also generate a dissonant accompanying pitch though none are as noticeable or bothersome as the one on D3.



Is this aliasing or some artifact from the sample or the result of the synthesis? Is there is fix? It doesn't go away when I modify the the sound sculpting parameters. In a full orchestra context it's not an issue but for solo and exposed passages it's a problem.



Thanks for any insight.

    Did you try a different sample rate (check for aliasing) ?

    Michael, my setup currently runs 24bit/48k. Changing to 44k makes no difference in regards to the noise. The noise is not present on all pitches so it seems if the problem was related to a global setting, they would all be affected.



    I've attached an mp3 of a solo horn playing quarter notes from G2 - C4, mezzo piano ascending and mezzo forte descending so you can hear what's going on. Be sure to listen on headphones or full-range speakers. As you'll notice, the distortion is most evident on D3, regardless of dynamic. There is also distortion in A3 and B3, a phasing type of sound, whereas the noise in D3 is a lower pitch.



    The distortion is present on all four horns, in exactly the same places, and regardless of dynamics. I'm not clear if the four horns are originally four different instruments played by four different musicians but the consistency of the noise leads me to think they are varied versions of one original sampling session.

    As I am simply a user, and hence not inclined to try an in-depth analyze on this, you should write to the SampleModeling support.

  • Hi Douglas,



    no problems here... Please contact our support and send us those few notes as a MIDI file. Only this way we can exclude any issues with your audio chain or the MIDI setup.



    Thank you.

    Peter, I sent a message via the contact page. I see that tech support is handled through Native Instruments but I'm hoping someone at Sample Modeling can address the problem.



    I didn't see a way to attach files but the audio file is here in my post for reference.



    I take from Michael's response and no other comments that this has not been a common issue. I trust a solution can be discovered as these are the best horns I have.



    Thank you.

    I don't even have a single Kontakt based Sample Modeling instrument.



    Sorry for unsuccessfully trying to be helpful :(

    I don't have this library so I don't have a baseline, but I don't hear anything strange about the sample you provided. I do hear what sounds like an accurate representation of the inconsistencies of the notes played by the real instrument. I might even hear the occasional "buzzing" that happens on the instrument, but is usually lost in a hall/stage setting.



    Any word from Sample Modeling on this?

    I thought it was just me, but I don't hear anything either. But I didn't want to say anything in case someone blamed my ears for not hearing it.



    I listened numerous times in my studio on good high-end monitors.



    Maybe if it doesn't seem to be in the recording itself, then there is something about your listening environment that is causing certain frequencies to be exaggerated (speakers? or room?)
